Here is another factoid about a blazar galaxy!

When it points towards us it becomes super bright.

Here is a quick definition of gamma rays from wikipedia:

Gamma radiation, also known as gamma rays, and denoted by the Greek letter γ, refers to electromagnetic radiation of an extremely high frequency and therefore consists of high-energy photons. Gamma rays are ionizing radiation, and are thus biologically hazardous. They are classically produced by the decay of atomic nuclei as they transition from a high energy state to a lower state known as gamma decay, but may also be produced by other processes.

This galaxy lies in the constellation Boötes, approximately 7.6 billion light-years away, and has a black hole of about 70 million solar masses at its center.

If placed at the center of our own Solar System, the black hole’s event horizon would extend almost to the orbit of Mars.

NASA’s Fermi telescope detected gamma rays up to 33 billion electron volts (GeV). For comparison, visible light has energies between about 2 and 3 eV.

We’re looking forward to hearing more from the teams and new pics from the Fermi telescope.  And feel free to comment with your ideas about blazar galaxies.
